▎ 摘  要

NOVELTY - Oxidation-flame retardant and high shear force integration solid waste inorganic adhesive comprises 0.5-1.5 wt.% composite grinding auxiliary agent, 25-30 wt.% slag, 5-10 wt.% dust mud kiln slag, 5-10 wt.% high silicon bauxite, 10-15 wt.% phosphorus slag, 0.2-0.6 wt.% graphene oxide, 1-4 wt.% composite alkali activator, 25-30 wt.% hydrogen peroxide solution, and 10-20 wt.% semi-dry desulfurization ash. The composite grinding auxiliary agent is a mixture of glycerol, anhydrous ethanol and tripoly glycerol. The slag, dust mud kiln slag, high silicon bauxite, phosphorus slag, and semi-dry desulfurization ash are industrial solid wastes. The graphene oxide is graphene oxide of Brodie method, graphene oxide of Staudemaier method or graphene oxide of Hummers method. The composite alkali activator is a mixture of sodium silicate, and sodium hydroxide, where sodium silicate and sodium hydroxide are industrially pure. The hydrogen peroxide solution is a mixture of hydrogen peroxide and water. USE - Used as oxidation-flame retardant and high shear force integration solid waste inorganic adhesive. ADVANTAGE - The adhesive: reduces production cost; improves flame retardancy and shear force; promotes transition from unstable calcium sulfite in semi-dry desorption to stable calcium sulfate; realizes integration of oxidized flame retardant and high shearing force; greatly enhances market competitiveness and application scope; and expands large-scale, and high value-added applications of slag, dust slag kiln slag, high silica bauxite, phosphate slag and semi-dry desulfurization ash. DETAILED DESCRIPTION - Oxidation-flame retardant and high shear force integration solid waste inorganic adhesive comprises 0.5-1.5 wt.% composite grinding auxiliary agent, 25-30 wt.% slag, 5-10 wt.% dust mud kiln slag, 5-10 wt.% high silicon bauxite, 10-15 wt.% phosphorus slag, 0.2-0.6 wt.% graphene oxide, 1-4 wt.% composite alkali activator, 25-30 wt.% hydrogen peroxide solution, and 10-20 wt.% semi-dry desulfurization ash. The composite grinding auxiliary agent is a mixture of glycerol, anhydrous ethanol and tripoly glycerol in a mass ratio of 4:2:1-1:1:1, where, glycerol, absolute ethanol and tripoly glycerol are analytically pure. The slag, dust mud kiln slag, high silicon bauxite, phosphorus slag, and semi-dry desulfurization ash are all industrial solid wastes. The graphene oxide is graphene oxide of Brodie method, graphene oxide of Staudemaier method, or graphene oxide of Hummers method. The composite alkali activator is a mixture of sodium silicate, and sodium hydroxide in a mass ratio of 1:3-3:1, where the sodium silicate is industrially pure having modulus of 0.8-1.6, and sodium hydroxide is industrially pure. The hydrogen peroxide solution is a mixture of hydrogen peroxide and water in a mass ratio of 10:1-10:3, where hydrogen peroxide is industrially pure.
